Though Paramount has yet to release the TV spot for M:I:3 online, Disney was ever so kind.
Dead Man's Chest and Cars TV Spots
The TV spot for Cars was cool because it showed off a bunch of new scenes from the Pixar/Disney animation. Like all new Pixar films before it, Cars looks like the next step in incredible CG animation.
The TV spot for Pirates of the Caribbean: Dead Man's Chest was simply crazy; in the best way. Though I would love to hear a little bit more of the original music from Klaus Badelt in the trailers for the sequel, I still have to admit that the music chosen fits the kinetic style of the trailer.
The TV spot for Pirates also gives us a sharp look at the sea creature that surfaces with what looks to be a human; or something close to it. Though it is cool, I still can't tell what the hell the creature is.
